I've just purchased the new SE of Monkey Island 2 using stream.
Now I have couple of questions .

1. Do I have (MUST) use stream to start the game ? I mean , after it's already on my computer why can't I start it just like any other game I purchased.
2. I know that I can use offline mode. I've chosen to start in offline mode , but still ; when I start the game it's trying to connect to stream and check for updates (although I've disabled this option under the game properties in stream games list).
3. MOST Important !!! : I've played the game for about an hour , saved my status couple of times (used 5 slots) and exit the game.
Today , when starting the game again , I couldn't find any saved games from yesterday , and the only option was to start a new game.
4. Is there a retails version to purchase ?

Also -- Everything that was already available under "Achivments" was gone.

I read on the site that the games are being saved also on the stream network . But also after going online to my account on stream I couldn't see it.
